Abstract：For digital measurement demands of the structure and equipment installation in the internal and external
regional space, the associate technology of inside and outside reference points is researched. The internal measurement accuracy
field united with the external measurement accuracy field is constructed. With regard to different openings between
inside and outside spaces, utilizing the multi-spotting method, two measurement points and a level single-station positioning
method, two measuring points and a level two-station positioning method, internal precision field is established to
achieve the unity with external precision field. In a certain type of equipment, for example, experiment results show that the
inconsistent measurement error of the same checkpoint between inside and outside measurement accuracy fields is up to 0.14
mm, which proves that the build mode is feasible, simple and reliable.
